...Judith O. Nwerem; Nwachukwu Romanus Ekere; Cynthia N. Ibeto; Chigozie E. Ezechi; Janefrances N. Ihedioha; Hillary O. Abugu Kinetics and modelling of organic pollutants biodegradation in Ajali River was studied. Dissolved oxygen ( DO ) was determined using Winkler-Azide method, while biochemical...

..., and 10 mg/l fluoride concentration. The Freundlich model (R² = 0.9274) described multilayer adsorption, and the pseudo-second-order model (R² = 0.9921) provided a comprehensive insight into F⁻ adsorption kinetics. The thermodynamic examination confirmed...

.... It has been observed that Monod's equation effectively defined the cell growth behaviour within the lead concentration range of 0.05–0.25 kg lead/m³. Notably, the experiment was also facilitated the derivation of essential intrinsic kinetic parameters, such as the maximum specific cell growth...

..., diatomite masses and MG concentrations at a temperature of 25°C. Equilibrium, kinetics and thermodynamic characteristics were also studied. The results show that the diatomite consisted of an integrated and nearly circular sieve plate with many small ordered pores, giving it a high specific surface area...

...⁺)) by using the adsorption mechanism. Adsorption parameters, such as contact time, dose and initial concentration of the heavy metal ions, were investigated. Five adsorption models (two and three parameters) were studied. Also, the adsorption kinetics through the intraparticle diffusion model was applied...

....) were used as a renewable and low cost biological adsorbent for the removal of textile metal complex dye from aqueous solutions. Batch experiments were carried out for sorption kinetics and isotherms. Experimental operating variables studied were pH, contact time at different initial dye concentrations...
